DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] Embodiments of the present invention will now be described,
by way of example only, with reference to the accompanying
drawings.
First Embodiment
[0028] As shown in FIG. 1 to FIG. 3, the present invention
discloses a shower head flow control structure, comprising a water
inlet assembly 1, a sealing seat 2, a primary flow restrictor 3,
and a plurality of secondary flow restrictors 4.
[0029] The water inlet assembly 1 has a water inlet passage 121
communicating with a water supply tube. The water inlet assembly
may be a shower head connector, or a water inlet structure composed
of a ball joint 11 and a ball joint holder 12. A lower end of the
ball joint 11 is fixed to the ball joint holder 12. The ball joint
holder 12 is provided with the water inlet passage 121.
[0030] The sealing seat 2 is sealedly connected to a lower end of
the ball joint holder 12 of the water inlet assembly 1. The sealing
seat 2 has a plurality of discharge holes 21. The inlet water
passage 121 communicates with one of the discharge holes 21.
[0031] The primary flow restrictor 3 is disposed in the water inlet
passage.
[0032] The secondary flow restrictors 4 are disposed in the
discharge holes 21, respectively. The flow rate of the primary flow
restrictor 3 is greater than the flow rates of the secondary flow
restrictors 4. The flow rates of the secondary flow restrictors 4
are different from each other.
[0033] In this embodiment, the flow rate of the primary flow
restrictor 3 is 2.5 GPM. The number of the discharge holes 21 is
two, and the number of the secondary flow restrictors 4 is also
two. The flow rate of one of the secondary flow restrictors 4 is
2.0 GPM, and the flow rate of the other secondary flow restrictor 4
is 1.75 GPM. As shown in FIG. 3, the primary flow restrictor 3 is
provided with an O-shaped ring 7 for controlling the water flow.
Using the O-shaped ring 7 to control the water flow is a common
flow control means. Each of the secondary flow restrictors 4 is
provided with an O-shaped ring 7 or a flow control element 9 for
controlling the flow of water. Using the flow control element 9 to
control the water flow has a better water flow stability. Referring
to FIG. 9 and FIG. 10, the circumferential wall of the flow control
element 9 is formed with six notches 91 spaced equally. The flow
control element 9 is provided with a plurality of vertical through
holes 92. Between the flow control element 9 and the bottom surface
of the secondary flow restrictor 4 is defined as a water effluent
area. The water flows through the notches 91 of the circumferential
wall of the flow control element 9 and the through holes 92. The
water flows from the water effluent area and the through holes 92
to the discharge holes 21. Since the flow control element 9 is a
rubber element, the water inlet position of the flow control
element 9 is deformed under water pressure. When the water pressure
is low, the water inlet position of the flow control element 9 is
not deformed, and the water may flow through the notches 91 to the
discharge holes. When the water pressure is high, the water inlet
position of the flow control element 9 is compressed to become
smaller, the water effluent area is closed, and the water passes
through the through holes 92 only so as to provide uniform water
flow when the water pressure is high or low.
[0034] The flow rate of the primary flow restrictor 3 and the flow
rate of the secondary flow restrictor 4 are not limited to the
embodiments of the present invention. According to different spray
patterns and water flow requirements, the flow restrictors of
different flow rates can be used.
[0035] It should be clear to the person skilled in the art that the
"flow control element" described in the present invention functions
as an O-shaped ring 7 for controlling the water flow, that is, the
"flow control element " is a common name in the sanitary ware
industry.
[0036] As shown in FIG. 1-3, in order to facilitate the
installation of the sealing seat 2 and the switching of the spray
patterns, the shower head flow control structure of this embodiment
further includes a rotation support seat 5. The upper end of the
sealing seat 2 and the lower end of the water inlet assembly 1 are
fitted into the rotation support seat 5. Through the rotation
support seat 5, the sealing seat 2 is rotatably connected to the
lower end of the ball joint holder 12 of the water inlet assembly
1. In order to ensure the stability of the water flow, the lower
end of the water inlet passage 121 is provided with a gasket 8. The
gasket 8 communicates with one of the discharge holes 21. The
gasket 8 and a sealing gasket are common sealing elements in the
field of sanitary ware equipment. The role of the gasket 8 in the
shower head of the present invention is to ensure that the water
flows from the water inlet passage 121 to the discharge holes 21
smoothly.
[0037] Referring to FIG. 2 and FIG. 3, in this embodiment, the
shower head flow control structure further includes a faceplate 6.
The faceplate 6 is connected to the lower end of the sealing seat 2
in a manner that can drive the sealing seat 2 to rotate relative to
the water inlet assembly 1. In order to further simplify the
switching operation of the spray patterns, the side of the
faceplate 6 is provided with a rotation handle 61.
[0038] Further, the secondary flow restrictor 4 may be rotatably
mounted in discharge hole of the sealing seat in a detachable
manner. The secondary flow restrictor 4 may be integrally formed in
the discharge hole 21.
Second Embodiment
[0039] As shown in the figures, the second embodiment is
substantially similar to the first embodiment with the exceptions
described hereinafter. The number of the discharge holes 21 is
three, and the number of the secondary flow restrictors 4 is also
three. The flow rate of one of the secondary flow restrictors 4 is
2.0 GPM, the flow rate of another secondary flow restrictors 4 is
1.75 GPM, and the flow rate of the other secondary flow restrictor
4 is 1.5 GPM.
[0040] Although particular embodiments of the present invention
have been described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the present invention. Accordingly, the
present invention is not to be limited except as by the appended
claims.
